Here, the embodiment of the present invention does not describe the specific structures of the primary filter 126, the secondary filter 127, and the flow equalizing part 128, and in the specific implementation, a person skilled in the art can select the type according to actual needs as long as the use requirements can be met. Taking the flow equalizing member 128 as an example, it may be a perforated plate, a louver, a grating plate, or a flow equalizing membrane, etc., which can guide the incoming flow of the secondary filter 127 uniformly into the operating chamber, so as to avoid the formation of turbulent flow as much as possible and facilitate the cleanliness control.

Taking the case where the air chamber 12 blows air into the operation chamber 21, the primary filter 126 is a primary filter, and is installed at a different position from the secondary filter 127, and different filter devices can be selected in terms of filtering performance.

The secondary filter 127 and the flow equalizing part 128 are detachably mounted on the second air cavity 124, so that the maintenance and the replacement can be facilitated. The specific detachable connection mode is various, and in practical application, a person skilled in the art can select the detachable connection mode according to specific needs, for example, the detachable connection mode can be a screw connection mode, a clamping connection mode, an overlapping connection mode and the like.

When the wind turbine is installed, the flow equalizing parts 128 can be butted and overlapped with and supported on the installation frame to cover the ventilation openings of the installation frame, so that the flow equalizing treatment can be carried out on the wind passing through the ventilation openings; when the flow equalizing device is required to be disassembled, one of the flow equalizing members 128 can be lifted upwards firstly, so that the flow equalizing member 128 and the other flow equalizing members 128 are staggered in the vertical direction, then the flow equalizing member 128 and the other flow equalizing members 128 can be stacked in the vertical direction by moving the flow equalizing members 128, at this time, part of the ventilation opening can be exposed, and each flow equalizing member 128 can be disassembled from the mounting frame by lifting the other flow equalizing members 128 upwards and inclining for a certain angle. The detachable connection mode does not need any connecting piece, has simple installation structure and can more conveniently disassemble and assemble the flow equalizing part 128.

As for the mounting structure of the secondary filter 127, in an exemplary scheme, as shown in fig. 6, a plurality of connecting pieces 127a may be provided on the chamber wall of the second wind chamber 124, specifically, a connecting frame 12f may be provided on the chamber wall of the second wind chamber 124, the connecting pieces 127a may be provided on the connecting frame 12f, the connecting pieces 127a may be sleeved with a connecting tube 127b capable of rotating relative to the connecting pieces 127a, a supporting body 127c is connected to an outer wall of the connecting tube 127b, and the secondary filter 127 may be supported on the supporting body 127c in a lap joint manner.

With such arrangement, when the secondary filter 127 needs to be detached, the secondary filter 127 only needs to be lifted upwards to remove the pressing effect on the support body 127c and the sleeve 127b, and then the support body 127c and the sleeve 127b are rotated to enable the support body 127c to avoid the secondary filter 127, so that the secondary filter 127 can be detached; the detachable connection scheme has the advantages that the structure is simple, the operation tool is not needed, the disassembly and the assembly can be directly completed manually by a user, and the disassembly and the assembly are convenient and fast.

In detail, the connecting member 127a may include a shaft portion and a head portion, the radial dimension of the head portion may be larger than that of the shaft portion, the shaft portion may be provided with external threads, the connecting cylinder 127b may be sleeved on the shaft portion and may abut against the head portion, and in this connecting structure, the shaft portion may be connected with the connecting frame 12f in a threaded manner, or may be connected with the connecting frame 12f by matching with a nut member. In addition, a through hole may be provided in the connecting frame 12f, and then the rod portion of the connecting member 127a may be inserted through the through hole and abutted against the connecting frame 12f through the head portion, and a nut member may be screwed on the rod portion of the connecting member 127a to lift and support the sleeve 127b, so that the above-mentioned detachable connecting structure may also be formed.

Further, an inner circulation air passage 131 may be further included, an inner circulation air opening (not shown) may be further provided on the chamber wall of the first air chamber 123, and one end of the inner circulation air passage 131 may be connected to the inner circulation air opening, and the other end may be communicated with the operation chamber 21.

Of course, all fresh air may be used, and in this case, the air in the operation room 21 may be directly discharged through the waste air discharge passage 132, which is also applicable. As shown in fig. 7, both the internal circulation air passage 131 and the exhaust air passage 132 may be integrated into the rear cover assembly 13.

The walls of the plenum 12 may be provided with openable and closable access doors (not shown) for access to components within the plenum 12, such as the primary filter 126, plenum box 122, etc., as previously described. The access door can be opened and closed by referring to the aforementioned isolation door 212a, material door and door 214, and a repetitive description thereof will not be given here.
